This question already has an answer here:
When a user tries to post a new question on Stack Overflow for the first time, he's redirected to this page.
For a new user who is usually not very patient, it's just a wall of text. He goes over the words quickly, ticks the obvious "thanks, I will keep these tips in mind when asking " checkbox and then he might easily miss the "proceed" link which is both aligned to the right, far far away from the checkbox and has a light gray color.
In such a case the user will scan the page again looking how to get past that obstacle, then to the right of the big search box he'll see this:
Now he thinks "great, let's discuss my question on meta (whatever meta is)" and click the link happily and full with hope. He gets to a site with a very similar design to Stack Overflow. Remember that he's under the impression that's the place to discuss his question.
The "Ask Question" button is 100% the same as the one on Stack Overflow, so our dear user clicks it. Jackpot! There's no irritating wall of text asking him to confirm things he'll never really remember. He posts the question there and quickly forgets the bumpy way he went through... until his question is downvoted and deleted on that mysterious "meta" site he never really meant to reach in the first place.
What can we do? I'm open for suggestions or objections, if you don't think that's the source for many of the programming questions we see here on daily basis.
